Oura hits $5B valuation: Smart ring maker Oura has raised $75M in Series D funding from glucose monitoring giant Dexcom, boosting its valuation to over $5B. The partnership will integrate Dexcom's glucose data with Oura's health metrics, enabling users to track the impact of nutrition on their health, with the first app integration set for 2025. Oura, which has sold 2.5M rings and expects $500M in sales next year, is now competing with Apple's efforts in noninvasive glucose tracking. https://techcrunch.com/20.. #Gadgets
